<h1>klog</h1><p><span class="helptopic">Laplacian of Gaussian kernel</span></p><p>
<strong>k</strong> = <span style="color:red">klog</span>(<strong>sigma</strong>) is a 2-dimensional Laplacian of Gaussian kernel of
width (standard deviation) <strong>sigma</strong> and centred within the matrix <strong>k</strong> whose
half-width is H=3xSIGMA, and W=2xH+1.

</p>
<p>
<strong>k</strong> = <span style="color:red">klog</span>(<strong>sigma</strong>, <strong>H</strong>) as above but the half-width <strong>H</strong> is specified.
